Question

construct a rectangle ABCD , given that AB=5cm and the diagonal AC =6.5cm.​

Answer 1

given:-

AB=5

AC=6.5.

TO GET:-

ALL DIMENSIONS

DC=AB (opposite side of rectangle are equal)

(if we notice there are two right angle triangles ∆ABC , ∆ADC)

for BC , AD (width)

(USE PYTHAGORAS THEOREM)

H²=P²+B²

AC²=AB²+BC²

6.5²=5²+x²

6.5²+5²=x²

42.25+25=x²

67.25=x²

√67.25=x

x=8.2006
