2(L + B) = 24 So L+ B = 12 ------(1) & L = 5B ------(2) Putting 2nd equation in 1st ; we will get So 5B + B = 12 So 6B = 12 or B = 2cm So L = 5 × B = 5 × 2 = 10 cm So area of the rectangle = L× B = 10 × 2 =20 cm²
1885 ÷ 64.98 + 7.29 + ? = 69.09
(49 x ?) / 3.5 + 389 = 627
25% of 400 + 3 × 102 = ?2
15% of 2400 + (√ 484 – √ 256) = ?
√10000 x √8100 - (50)² = √(?) + (80)²
13.5% of (100 + ?) = 27
? = (22% of 25% of 60% of 3000) + 21
