Given -
A rectangle (big) of dimensions 36cm × 28 cm. (l×b¹)
Second small rectangle of dimensions 7 cm × 10 cm (l×bⁿ)
To find -
How many small rectangles can be cut out from the big rectangle
Solution -
How many small rectangle.. = Area of big rectangle ÷ area of small rectangle
= (l×b¹) ÷ (l×bⁿ)
= (36 cm × 28 cm) ÷ (7 cm × 10 cm)
= 1008 cm² ÷ 70 cm²
= 14.4
It means we can cut 14 small rectangles from big rectangle, We will think that 0.4 rectangle is wastage.
