Question

find the area of a triangular region whose base is 90 m long and the corresponding altitude is 45 m long

Answer 1

Heya!!!

This is your answer.

Given :-

Base = 90 m.
Altitude = 45 m.

We know that ....
area of triangle = 1/2×bh
$= \frac{1}{2} \times 90 \times 45 \\ = 45 \times 45 \\ = 2025 \: {m}^{2}$
Hence the area of given traingle is 2025 m².

Hope it helps
