The length of rectangle is 7 cm and breadth is 3 cm find its area and perimeter
please it is argent
please give me solutions
Answers
Answer:
Perimeter - 20cm
Area - 21 cm
Step-by-step explanation:
Length - 7cm
Breadth - 3cm
Perimeter - 2(l+b)
= 2(7+3)
= 2×10
= 20 cm
Area :- l×b
= 7× 3
= 21 cm²
Given: length of rectangle = 7 cm
breadth of rectangle = 3 cm
To find: area and perimeter of the rectangle
Solution: The formula for finding the area of a rectangle = length X breadth
Hence, area of the given rectangle = (7 X 3) sq. cm
= 21 sq. cm
The formula for finding the perimeter of a rectangle = 2(length + breadth)
Hence, perimeter of the given rectangle = 2(7 + 3) cm
= (2 X 10) cm
= 20 cm
