Find the area of a rhombus, each side of which measures 20 cm and one of whose diagonals is 24 cm.

Explanation

Length of rectangular grassy plot=112m long and Breadth = 78m
Therefore, the outside area of rectangular grassy plot`=LxxB=112xx78=8736 m^2`.
Total Area of Plot `= 8736m^2`
It has a gravel path 2.5 m wide all around it on the inside.
Then, Grassy area `=(112-5)(78-5)=7811m^2`.
Area of Path =Area of total plot − area of inside(grassy area) `=8736−7811=925m^2`
