Question

If the diagonal of a rectangle is 17 cm long and the perimeter of the rectangle is 46cm,then the area of the rectangle is

Answer 1

Answer:

120cm²

Step-by-step explanation:

A=p²/8 - d²/2

=46*46/8 - 17*17/2

=264.5-144.5=120cm²

A=l*b

=l*√(d²-l²)=P²/8 -d²/2

P=2(l+b)=2(l+√(d²-l²))

d=√(l²+b²)

where A=Area

l=length

b=breadth

d=diameter

p=perimeter
