Question

6. An isosceles triangle has perimeter 30 cm and each of the equal sides is 12 cm. Find the area of the triangle. ​

Answer 1

Answer:

Area of isisceles triangle=~37cmsqr

Step-by-step explanation:

Perimeter of isisceles triangle=30cm

length of equal sides are =12cm

let length of unknown side is x

perimeter= 12*2 + x

x=6cm

Area of triangle=1/2(base)(height)

area=1/2*6*height

height=sqrt(12*12 +3*3)

height=sqrt(153)

height=12.36

area=1/2*6*12.36

area=~37cmsqr
