Question

each of the equal sides of an isosceles triangle is twice the base and the perimeter is 75 cm find the length of the each side of rectangle

Answer 1

let x be length of base. so ATQ length of equal side =2x so lengths are 2x,2x,x and perimeter is 75cm. Then 2x+2x+x=75... 5x=75 i.e. x=15 hence the lengths are 30,30,15.

Answer 2

this is quite hard.
