Question

the base of an isosles triangle is 24cm and its area is 60 cm.find perimeter

Answer 1

Answer:

Perimeter = 50 CM

Step-by-step explanation:

Base = 24 CM

Area = 60 cm ²

Area = $\frac{1}{2}$bh

60 = $\frac{1}{2}$ x 24 x h

60 = 12 x h

h = 60/12

h = 5 CM

(hypotenuse)²= (12)²+(5)²=169cm

h = hypotenuse=√169=13cm

In an Isosceles triangle b = c = 13 cm

So Perimeter = 24 + 13 + 13 = 50 CM

Perimeter = 50 CM
