If area of a parallelogram with sides l and b is A and that of a rectangle with sides l and b is B then

What is the area of the rectangle with length l and breadth b?

If the area of the parallelogram with vec(a) and vec(b) as two adjacent sides is 15 sq. units, then the area of the parallelogram having 3vec(a)+2vec(b) and vec(a)+3vec(b) as two adjacent sides in sq. units is

In a parallelogram, the ratio of the two adjacent sides is 1 : 2. If the area of the parallelogram is 20 square units and the angle beween the two sides is 45^(@) , what is the area, to the nearest integer, of the rectangle having the sides equal to that of the parallelogram?

The maximum area of the rectangle whose sides pass through the vertices of a given rectangle of sides a and b is (a) 2(a b) (b) 1/2(a+b)^2 (c) 1/2(a^2+b^2) (d) non eoft h e s e

If the area of the parallelogram with veca and vecb as two adjacent sides is 15 sq unit ,than the area of the parallelogram having, 3veca + 2vecb and veca + 3 vec b as two adjacent sides in sq unit is

The maximum area of the rectangle whose sides pass through the vertices if a given rectangle of sides a and b is

The area of the parallelogram with vec a and vec b as adjacent sides is 20 sq. units. Then the areaof the parallelogram having 7 vec a + 5 vec b and 8 vec a + 11 vec b as adjacent sides is

The vector area of a parallelogram with bar(a) and bar(b) as adjacent sides is

The maximum area of the rectangle whose sides pass through the vertices of a given rectangle of sides aandb is (a) 2(ab)(b)(1)/(2)(a+b)^(2)(c)(1)/(2)(a^(2)+b^(2))( d) noneofthese

A rectangle and a parallelogram have equal areas. If the sides of a rectangle are 10 m and 12 m and the base of the parallelogram is 20 m, then the altitude of the parallelogram is
