Question

does u guys any one of these answers plz answer I only need one :)​

Answer 1

Step-by-step explanation:

22 . l= 22 m

b= ?

area = 440m²

Ares of rectrangle = L×B

440= 22× b

440/22= b

20= b

breath is 20m

perimeter of rectrangle = 2(l+b)

= 2 ( 22 + 20 )

= 2× 42

= 82m

perimeter of rectrangle is 82m

Answer 2

$\underbrace \text{Answer:}$

Question 21:-

Formula used:

• Interest:(P×R×T)/100
• Amount: Principal+Interest

Solution:

Given,

Principal= Rs.7500

Rate= 5%

Time= 2year

$\sf{Interest}= \frac{75 \cancel{00 }\times 5 \times 2}{1 \cancel{00} }$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 75 \times 5 \times 2$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \bf \red{Rs.750}$

Now,

$\sf{Amount} = rs.(7500 + 750)$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \bf \red{ rs.8250}$

⛬ The interest is Rs.750 and the amount is Rs.8250.
