Question

A triangle has an area of 21 cm^2 . Its base is 7cm long. Would all triangles with a base of 7 cm have an area of 21 cm^2? Explain.

Answer 1

Step-by-step explanation:

Answer 2

Area of a ∆ = 1/2 (b×h)

21cm²= 1/2( 7cm×h)

21cm²×2= 7cm×h

h= 21cm²×2/7cm= 3cm×2= 6cm

No, all the triangles with base 7cm will not have an area of 21cm² it also depends on the height.
