Question

14. The perimeter of a rectangle is 15cm and its width is 3.3/4cm. Find its length​

Answer 1

Answer:

6.67

Step-by-step explanation:

We know that,

$perimeter \: of \: the \: rectangle \: = 2(l + b) \\15 = 2(l + \frac{3.3}{4} ) \\ = 15 = 2l + \frac{3.3}{2} \\ = 15 - \frac{3.3}{2} = 2l \\ = \frac{30 - 3.3}{2} = 2l \\ = \frac{26.7}{2} = 2l \\ = \frac{26.7}{2 \times 2} = l \\ = \frac{26.7}{4} = l \\ l = 6.67$

Hope this will help you!!

Answer 2

Answer: L=6.675

Explanation-

Perimeter=2(L+B)

Perimeter= 2l+2B

Perimeter=2l+2*(3.3/4)

15=2l+1.65

13.35= 2l

l= 6.675
