Find Length and Perimeter

Answer 1

$<b><i>Heya!!!$

Given:
Area=480cm^2
Breadth =30cm

Solution:

Area=Length×Breadth
480= l (30)
l=480/30=16cm

Length=16cm

Perimeter=2 (l+b)
=2 (16+30)
=2 (46)
=92cm


Hope it helps^_^

Answer 2

area of rectangle = length ×breadth
480 cm²= length ×30cm
480/30= length
16cm = length

perimeter of rec. = 2×(length + breadth)
=2×(16+30)
=92cm.
