Answer 1

Answer:

Given

L2+B2= H2

(15)2+B2=(17)2

225+B2=289

B2=289-225

B2=64

B2=√64

B=8cm

Area of rectangle= L*B=15*8=120m square

Perimeter of rectangle=2(L+B)

= 2(15+8)

2(23)

46 cm

Answer 2

Answer:

perimeter of rectangle= 2×(length+breadth)

=2×(15+17)

=2×32=64 cm

Area of rectangle=length×breadth

=15×17

=275 cm^2
