Question

B) The perimeter of a rectangular painting is 310 cm.

If the length of the painting is 98 cm, what is its width?
Width of the painting: c cm

Answer 1

width = 57 cm.

Explanation:

length of rectangular painting = 98cm.

the perimeter of a rectangular painting=310cm

2( length + width ) = 310cm.

2×98 +2×width =310 cm.

196 +2× width =310 cm.

2×width= 310 - 196 cm.

2× width = 114 cm.

width = 114 / 2

= 57 cm.
