cm²

Answer 1

The area of the new triangle will be 90cm

How to find the area of a triangle

Given that the area of a triangle is expressed as:

A = 0.5bh

36 = 0.5bh

bh = 18

If the base and height are scaled by a factor of 5, then the area will be:

5(bh) = 5(18)

5(bh) = 90cm²

Hence the area of the new triangle will be 90cm²
