Area of the square = 225 cm2 Length of each side of the square = √225 = 15 cm Area of the rectangle = 225 + 125 = 350 cm2 Length of the rectangle = 10 + 15 = 25 cm So, area of rectangle = length × breadth = 25 × breadth = 350 cm2 So, breadth of the rectangle = 350/25 = 14 cm Therefore, perimeter of the rectangle = 2 × (length +breadth) = 2 × (14 + 25) = 78 cm
135 ÷ 3 of 5 = ? - 112
(? + 180 + 13 × 6) ÷ 20 + 3.5 × 512 (1/3) = 82
(392 + 427 + 226 – 325) ÷ (441 + 128 – 425) = ?
567-4824 ÷ 134 =? × 9
1/5 of 6/3 of 3/2 of 1966 = ?
2852 + 7848 + 2962 + 4268 = ? – 1460
Simplify the following expression:
(164-1)/17×15× (28+1)
?% of 140 + 16% of 250 = 62 × 12
(7/4×18/21)+ (51/7× 28/17) + (25/2 × 48/10) =?
60% of 120 – ?% of 64 = 20% of 200
