Question

The area if triangle is 0.48 cm2 and altitude as 8m. Find the base.​

Answer 1

As We Know

• $\sf \diamond \: \dfrac{1}{2} \times b \times h$

Putting Values According To Question,

• $\sf \dfrac{1}{2}\times b \times 0.8=0.48 {cm}^{2} \\ \\ \sf b×0.4=0.48 \\ \\ \sf \: b=\dfrac{.48}{0.4}=1.2dm$

Hence, the base of a triangle= 12 cm or 1.2 dm
