Question

Find the base of triangle whose: Area = 300cm height = 7.5cm​

Answer 1

b = 80 cm

Explanation:

• Find the base of triangle whose: Area = 300cm height = 7.5cm​

Area = 1/2b×h

Inverse formula

b = 2A : h

b = 2 × 300 : 7.5

b = 600 : 7.5

b = 80 cm

--------------

check

Area = 1/2 80 × 7.5

Area = 300 cm²
