Question

find the height of the triangle whose area is 38.9 metre square base is 8.5 metre​

Answer 1

Area=(1/2)×b×h

38.9=(8.5×h)/2

h=(2×38.9)/8.5

h=9.15 metre

Answer 2

Answer:

$\large{\underline{\boxed{\sf Base = 9.15 \: m}}}$

Explanation:

Given that-

Area of triangle = 38.9 m²

Base if triangle = 8.5 m

We need to find the height of the triangle. Here we go:

$\text{Area of triangle} = \frac{1}{2} \times \text{Base} \times \text{height} \\ \\ \implies 38.9= \frac{1}{2} \times \text{Base} \times 8.5 \\ \\ \implies 77.8 = \text{Base} \times 8.5 \\ \\ \implies \text{Base} = \frac{77.8}{8.5} \\ \\ \implies \text{Base} = 9.15 \: \text m$

Hence, the base of the triangle is 9.15 metres.

A triangle is a closed figure made up of three lines. The area of right triangle is given by -

$\text{Area of triangle} = \dfrac{1}{2} * \text{Base} * \text{Height}$
