Question

find the answer for this question in pho​

Answer 1

Step-by-step explanation:

equation 1 multply by 5 and equation 2 multiply by 1

5x-5y=300

-5x+7y=-0

_________

0+12y=300

12y=300

y=300\12

y=25

put the y=25 in equatuon 1

x+25=60

x=60-25

x=35

so the length of regtangle park is 35 m and its breadth is 25 m

area of regtangle =

$= length \times breadth \\ = 35 \times 25 \\ = 875 {m}^{2} \\ \\ \: \: \: \: {m}^{2} \: \: \: \: \: \: \: \: \: \: \: </strong><strong>rupees</strong><strong>.</strong><strong> \\ \\ \: \: \: \: 1 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 20 \\ \\ \: \: \: 875 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ? \\ \: \: = \frac{20 \times 875}{1} \\ \: \: = 17500 \: \: \: </strong><strong>rupees</strong><strong> </strong><strong>\:$
