Question

The area of a triangular field is 900msquare what is the base of the triangle if the height is 60m

Answer 1

Area formula of a triangle is:
A =
`(1)/(2)`bh
We know the are and the height, so substitute to find the base
900 m² =
`(1)/(2)` × b × 60 m
900 = 30b
Divide by 30 to isolate b

`(900)/(30) = (30b)/(30)`
30 and 30 cancels out
b = 30 m

Base of this triangle is 30 m
