Question

the area of an isosceles triangle is 300 CM square the height of the triangle is 15 cm find the perimeter of the triangle​

Answer 1

Answer:

Perimeter = 90cm

Step-by-step explanation:

Height of triangle, h=15cm

Area of triangle=300cm^2=1/2×b×h

b=600/15=40

base of triangle, b=40

Now, taking the Pythagoras theorem;

hypotenuse^2= root[(base/2)^2+(height)^2]

hypotenuse^2= root [(20)^2+(15)^2]

hypotenuse= 25

perimeter of triangle=2×25+40=90cm.
