Question

find the area of triangle whose base is 90m long and corresponding altitude 45m long​

Answer 1

Heya!!!

This is your answer.

Given :-

Base = 90 m.
Altitude = 45 m.

We know that ....
area of triangle = 1/2×bh
\begin{lgathered}= \frac{1}{2} \times 90 \times 45 \\ = 45 \times 45 \\ = 2025 \: {m}^{2}\end{lgathered}=21​×90×45=45×45=2025m2​ 
Hence the area of given traingle is 2025 m².

Hope it helps

Answer 2

Base = 90 m

Altitude = 45m

Area of trian. ½ base ×hieght

½×90×45

45×45

2025 m² answer
