Question

15 In an isosceles triangle, the length of each of the equal sides is 2 more than the length of the base.
If the ratio of the base to the perimeter of the triangle is 2.7, find the dimensions of the isosceles
triangle​

Answer 2

Answer:

Let the measurement of base be x

then, the 2 bigger sides are = x+2 and x+2

then their perimeter sum of all sides is

= base + 2 sides

=X +( X + 2) +(X+2)

= 3x+4

perimeter is 3x+4

the ratio of base and perimeter is given 7:2 base= X and perimeter is 3x+4

according to their ratio we can write

7(x)=2(3x+4)

then 7x =6x+8

= 7x-6x=8

so , we found that x=8

then base = X = 8

and other sides=X+2 and X+2

= 10,10 then three sides are =8,10,10
