Step-by-step explanation:

<h3><u>★ Solution :-</u></h3>

\sf \longmapsto 98^2

\sf \longmapsto (a - b)^2 = a^2 - 2ab + b^2

Here,

  • a = 100
  • b = 2

\sf \longmapsto (100 - 2)^2 = 100^2 - 2(100)(2) + 2^2

\sf \longmapsto 100^2 - 2(100)(2) + 2^2

\sf \longmapsto 10000 - 400 + 4

\sf \longmapsto 9606

Define a variable write an equation and solve the problem. the width of a rectangle is 3 meters more than one-fourth its length.
sweet [91]

Let's assume

length of rectangle is L

width of rectangle is W

the width of a rectangle is 3 meters more than one-fourth its length

so,

W=3+\frac{1}{4} L

the perimeter is 10 meters more than twice its length

we know that

perimeter =2(L+W)

so, we get

2(L+W)=10+2L

now, we can simplify it

2L+2W=10+2L

subtract both sides by 2L

2L+2W-2L=10+2L-2L

2W=10

W=5

now, we can find L

5=3+\frac{1}{4} L

subtract both sides 3

5-3=3-3+\frac{1}{4} L

2=\frac{1}{4} L

multiply both sides by 4

4*2=4*\frac{1}{4} L

L=8

so,

length of rectangle is 8 meter

width of rectangle is 5 meter ............Answer
