The perimeter of a rectangle is 26 cm and its length is 7 cm. Find its area in cm2..
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 42.
Perimeter (P) = 26 cm , Length (L) = 7 cm
Perimeter formula:
2 × (L + W) = 26
L + W = 13
7 + W = 13
W = 6 cm
Area = L × W = 7 × 6 = 42 cm²
