Question

the area of isosceles triangle is 300 cm2 the height of the triangle is 15 find the perimeter of triangle​

Answer 1

Area = 1/2× base×height

300=1/2× base×15

base= 600÷15

base= 40cm

Now; one of the equal side = root( 15^2 + 20^2) (half of base)

One equal side = 25 cm

So Perimeter of isosceles triangle :

25+25+40 cm = 90cm

Hope it helps.
