I NEED HELP! The perimeter of a rectangle is 26 cm. What are the dimensions of the rectangle if the area is 30 cm?

The answer is 3 and 10 because for perimeter we add all 4 sides which is 3 + 3 + 10 + 10 which equals 26 and area is length * width which is 3 * 10 = 30.

The length of the rectangle is 10 or 3 and the breadth of the rectangle is 10 or 3.

Given that, the perimeter of a rectangle= 26 cm and the area of a rectangle=30 cm².

What is the formula to find the area of the rectangle?

The formula to find the area of the rectangle is Area=Length×Breadth.

Now, Perimeter=2(Length+Breadth)=2(l+b)

⇒26=2(l+b)

⇒l+b=13 cm

⇒l=13-b

Area=l×b

⇒l×b=30 cm²

Now, (13-b)×b=30

⇒13b-b²=30

⇒b²-13b+30=0

⇒b²-10b-3b+30=0

⇒b(b-10)-3(b-10)=0

⇒b=10 or 3

Therefore, the length of the rectangle is 10 or 3 and the breadth of the rectangle is 10 or 3.
