The area of `triangleABC` is `8 cm^(2)` in which `AB=AC=4 cm` and `angleA=90^(@)`.

A

true

B

false

C

can not detemine

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
We have, `ABC` is a right angled triangle at `A`, where sides are given `AB=AC=4 cm`
`therefore" ""Area of a triangle "ABC=(1)/(2)("Base"xx "Height")=(1)/(2)xxACxxAB=(1)/(2)xx4xx4=8 cm^(2)`
