Question

the area of a triangle is equal to the square whose side measure 60 cm find the side of the triangle whose corresponding altitude is 90m

Answer 1

Ans . Area of triangle =Area of square

Side of square = 60

Area of square=sxs

= 60x60=3600cm^2

Then area of triangle =3600

1/2×b×h= 3600

Altitude of triangle=90cm

1/2×b×90= 3600

b=3600/45

b=80cm

Side of the triangle = 80cm
