Step-by-step explanation:
length of frame = 34 cm
width of frame = 18 cm
area of frame = l × b
= 34 × 18
= 612 sq cm
width of edge = 2 cm
length of frame with edge on both sides
= 34 + 4 = 38
breadth of frame with edge on both sides
= 18 + 4 = 22
area of frame with edge
= 38 × 22
= 836 sq cm
area of edge
= 836 - 612
= 224 sq cm
cost of edging @ Rs. 5
= 224 × 5
= 1120
total cost of edging = Rs. 1120
