Half of the perimeter of a rectangle is 30 cm. If the length of the rectangle is 6 cm more than its breath, then what is the area of the rectangle ? |
216 cm2 250 cm2 185 cm2 195 cm2 |
216 cm2 |
We know that, Perimeter of the rectangle = 2 (length + breadth) If half of the perimeter of the triangle = 30cm Then full perimeter of the triangle = 60 cm Now it is given that, the length of the rectangle is 6 cm more than its breath. Then let the value of breadth = x then the length will be x+ 6 Now, 2(x + x + 6) = 60 2x + 6 = 30 2x = 24 x = 12 = breadth x + 6 = 18 = length. Now the area of the triangle = 12 × 18 = 216 cm2
