Using formula, Perimeter of rhombus = 2 √(d1² + d2²) Where d1 & d2 are diagonals Therefore 2 √(d1² + d2²) = 74 ⇒ √(d1² + d2²) = 37 Squaring both sides, ⇒ (d1² + d2²) = 1369 ⇒ 12² + d2² = 1369 ⇒ 144 + d2² = 1369 ⇒ d2² = 1369 – 144 = 1225 Therefore, d2 = √1225 = 35 Therefore, area of the rhombus = 1/2 x d1 x d2 ⇒ 1/2 x 12 x 35 = 210 m²
(22² × 8²) ÷ (92.4 ÷ 4.2) =? × 32
{(123 + ? × 28) – 1254} × (2328 ÷ 97 – 13) = 8195
Solve for ?.
?² = 37% of 800 – 14 × 18+ 5! - 20
6612 ÷ 19 - ?% of 240 = -2196
(1/8) × (256 × 2)/(8 × 4) + ?3 = 1730
Simplify the following expression:
84 - [21 - {14 - (25 - 16 + 8) }] ÷ 3 X 6
4? + 82 = 22% of 300
779 + 136 – 334 = 270 + 121 + ?
