Question

find the perimeter, area and lenght of diagonal of a rectangle, having : lenght = 15 cm, breadth = 8cm​

Answer 1

Answer:

Perimeter=46cm

Area=120sq cm

Length of daigonal=17cm

Step-by-step explanation:

l=15cm

b=8cm

Perimeter=2×(l+b)

=2×(15+8)

=2×23

=46cm

Area=l×b

=15×8

=120sq cm

Let d be the length of daigonal

d^2=l^2+b^2

=(15^2)+(8^2)

=225+64

=289

d=17cm

Hence, the perimeter, area and length of daigonal are 46cm, 120 sq cm, and 17cm respectively.
