A rectangle has a perimeter of 34 cm in an area of 52 cm squared it's length is 5 more than twice its width write and solve the

valina [46]

Let $l$ be the length and $w$ be the width of the rectangle.

Given perimeter of the rectangle

$2(l+w)=34 \; l+w=17$

Area of the rectangle is

$lw=52$

Also length is 5 more than twice its width,

$l=2w+5$

From the above equations

$(l-w)^2=(l+w)^2-4lw=17^2-4*52=81\\ l-w=9,\; since \; l>w$

Now $2l=9+17=26\;,l=13,w=4$

The dimensions of the rectangle are length $l=13$ , and width $w=4$ .

vladimir2022 [97]

Answer:

At the end krisi will receive 550

Step-by-step explanation:

We have given that krisi took $500

So the principle amount P = $500

Rate of interest r = 5%

Time t = 2 years

We know that simple interest is given by

$simple\ interest=\frac{P\times r\times t}{100}=\frac{500\times 5\times 2}{100}=$50$

So the amount which he receive = 500 +50 =550

So at the end krisi will receive 550
