43) Length = 500 cm.
breadth = 75 cm.
area = ( 500 × 75 ) cm.
area =37, 500 cm.
border = 6 cm.
= 37, 500÷6
=6250 sq cm .
cost = rs (6250 × 0.50)
cost = rs 3125
44)Area of Trapezium = 1/2 × ( sum of parallel sides ) × hieght
912 = 1/2 × 6x + 13x × 24
912 = 19x × 12
19x = 912/12
19x = 76
x = 76/19
x = 4
6x = 24cm
13x = 52cm
