Question

In a sqauare ABCD, area of ∆ ABC = 40.5 cm². Length of each side of square is
​

Answer 1

Answer:

the sides of triangle ABC are:-

AB(side of square)

BC( side of square)

AC( diagonal)

triangle ABC is a right angles triangle as the sides of square are perpendicular to each other

area of triangle ABC=1/2xbasexheight

40.5=1/2xABxBC

40.5x2=(AB)^2. [ since AB=BC=side of square]

AB^2=81

AB=side of square=9cm

Hope it helps
