Question
If the perimeter of rectangle is 48 cm and its length is
4 cm more than breadth then find its area?Solution
According to the question Let the length and breadth of rectangle are x cm and (x – 4) cm respectively. Perimeter of rectangle = 2 x (Length + Breadth) ⇒ 2 (x + x – 4) = 48 ⇒ x = 14 Length = x = 14 cm Breadth = x – 4 = 10 cm Area of rectangle = Length x Breadth Area of rectangle = 14 x 10 = 140 cm²
236.23 - 653.23 + 696.23 = ?
Simplify:
Simplify the following expression:
(506 ÷ 22 + 9 × 3) × ? = 900 ÷ 9
What will come in place of (?) in the given expression.
√625 + 12 × 5 = ?[(15)³ × (8)²] ÷ (90 × 6) = ?²
(√529 + 63 /8)% of 800 = ?% of 250
(15 × 225) ÷ (45 × 5) + 480 = ? + 25% of 1240
Simplify the following expression:-
25% of {(5/18) × 2880 + 122 } = ?% of 590
