Question

the base and height of the triangle aee in ratio 4:5. If the area of tye triangle is 90sqcm, dind the measure of its base and height.​

Answer 1

Answer:

bass = 12cm

height = 15cm

Step-by-step explanation:

Given,

bass : height = 4:5, then

let,

bass = 4x, and height = 5x

Now,

area of triangle = 1/2.bass.height

90cm² = 1/2.4x.5x = 10x²

x² = 9, x = 3cm.

putting value of x = 3

so,

bass = 4x = 4×3 = 12cm, and

height = 5x = 5×3 = 15cm.
