Question

5. The area of a rectangular field is 3000 m².
If it be 37 m 50 cm wide, find its length
and perimeter.​

Answer 1

Step-by-step explanation:

$\huge \boxed{ \pink{QUESTION}} \\ area = 3000 {m}^{2} \\ width = 37m \: 50cm \\ = 37m + 0.5m \\ = 37.5m \\ length = {?} \\ perimeter = {?} \\ area = 3000 \\ length \times width = 3000 \\ length = \frac{3000}{37.5} \\ = 80m \\ perimeter = 2(length + width) \\ = 2(80 + 37.5) \\ = 2 \times 117.5 = 235m \\ \\ \huge \boxed{ \red{formulas}} \\ area \: of \: rectangle \: = l \times b \\ perimeter \: of \: rectangle = 2(l + b) \\ diagonal \: of \: rectangle = \sqrt{ {l}^{2} + {b}^{2} } \\ \\ l = length \\ b = breadth$

Answer 2

Answer:

Area=l*b

l=Area/breadth

length=3000/37.50

=300000/3750

=30000/375

=80m

Perimeter of rectangle

=2 (l+b)

=2 (80+38.5)

=2*118.5

=237 m

Hope it will help you.
