Question

A playground is 16 m long and 25 metre wide find the cost of fencing the ground at the rate of rupees 5.25 per metre

Answer 1

Step-by-step explanation:

the perimeter of rectangle is 2(l+b)

2(25+16)

2×41

82

the cost of fencing per m =5.25$

82×5.25

=430.5ruppes

Answer 2

$\huge \purple{ \underline{ \boxed{ \red{ \mathbb{ANSWER : }}}}}$

$\red{ \textsf{The cost of planting grass on the playground is \orange{Rs.2100 .}}}$

$\huge \purple{ \underline{ \boxed{ \red{ \mathbb{EXPLANATION : }}}}}$

$\large\green{ \underline{ \underline{ \mathbb{GIVEN : }}}}$

$\orange{ \textsf{Length of playground = 16 m }}$

$\orange{ \textsf{Breadth of playground = 25 m }}$

$\orange{ \textsf{Cost of planting grass per m² = Rs.5.25}}$

$\large\green{ \underline{ \underline{ \mathbb{FORMULA \: USED : }}}}$

$\orange{ \textsf{Area of rectangle = Length x Breadth}}$

$\large\green{ \underline{ \underline{ \mathbb{SOLUTION : }}}}$

$\red{ \textsf{Area of playground = Length x Breadth}}$

$\red{ \textsf{Area of playground = 16 x 25}}$

$\red{ \sf{Area \: of \: playground = 400 \: {m}^{2} }}$

$\red{ \textsf{Cost of planting grass per m² = Rs.5.25}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 400 \: m² = 400 \times 5.25}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 400 \: m² = Rs. \: 2100 }}$

$\large \green{ \underline{ \underline{ \mathbb{KNOW \: MORE : }}}}$

$\orange{\mathbb{AREA : }}$

The area is the measurement of space enclosed by a closed geometric figure .
