Question

a painting with a dimension 140cm by 80 cm is to be framed with a 10cm wide frame all around its edges .if the frame painting is to be backed by hardboard, what is the area of the hardboard to be used?

Answer 1

length of the painting along with frame = 140+10+10=160 cm
breadth of the painting along with frame =80+10+10=100 cm
therefore, area of the hardboard required = 160x100cmsquare = 16000cmsquare.
= 160/100 x 100 metresquare
=1.6 metresquare.
