Answer 1

Answer:

length of unequal side = 143 cm

perimeter of triangle =288 cm

Let the equal side of the triangle be x

then the equal side of triangle be 2×x=2x

=2x +143=288

=2x=288-143

=2x=145

=x=145÷2

= x=72.5

hence the length of the each equal side of the triangle if 72.5 cm

A/Q area of triangle =1/2× base ×height

height is not given so let the height if the triangle be x

so, 1/2×143×x

=71.5x² (answer)
