Question

two equal sides of an isosceles triangle are 4m less than 3 times the third side. find the dimensions of the triangle,if the perimeter is 55 m

Answer 1

ATQ, the two equal sides of the isosceles triangle is 4m less than the 3 times of the third side..

let the third side of the isosceles triangle be x.

therefore length of the other two equal sides = 3x - 4

perimeter of the isosceles triangle is given = 55m

therefore x + (3x - 4) + (3x - 4) = 55m

==> x + 3x - 4 + 3x - 4 = 55m

==> 7x - 8 = 55m

==> 7x = 55 + 8

==> 7x = 63

==> x = 63/7

==> x = 9

hence, dimensions of the isosceles triangle :-

3rd side = x = 9m

and length of the equal sides = 3x - 4

= ( 3 × 9 ) - 4

= 27 - 4

= 23m

dimensions are 9m, 23m and 23m.

HOPE THIS HELPS..!!
