Question

Base and height of a right angled triangle are in the ratio of 5:7 and area is
$70 {cm}^{2}$
Find the base and height of the triangle.​

Answer 1

Step-by-step explanation:

let base and height be 5x and 7x

Area of right =1/2×base×height

70cm^2= 1/2*35x^2

x^2=140/35=4

x=2

so base=5x= 10 cm

height= 7x=14cm
