Hamid has gained weight
he now weighs 88kg, which is 10% higher than his normal weight.
what is hamid’s normal weight?

80

Step-by-step explanation:

if 88 is 10% higher than his previous weight then his current weight is 110%

divide 88 by 110 then multiply it by 100 to find his previous weight

88 ÷ 110 × 100 = 80

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
