Question

A right angle triangle has an area of 91 cm and a perpendicular length of 13 cm . What is the length base ?

Answer 1

Given ,

• Area of right angled triangle = 91 cm²
• Height of triangle = 13 cm

We know that , the area of right angled triangle is given by

Area = 1/2 × base × height

Thus ,

91 = 1/2 × base × 13

7 = 1/2 × base

base = 14 cm

$\sf \therefore \underline{ The \: base \: of \: triangle \: is \: 13 \: cm}$
