Question

1. A photograph of sides 35cm by 22cm is mounted a frame of external dimension 45cm by 30 cm. find the area of the border surrounding the photograph.

2. The adjacent sides of a parallelogram are 36cm and 27cm in length. if the perpendicular distance between the shorter sides is 12cm, find the distance between the longer sides.

Answer 1

Answer:

area of the photograph=35*22=770 sq cm

area with external dimension =45*30=1350 sq cm

so, area of the border=(1350-770)sq cm

= 580 sq cm
