Answer 1

$\bigstar$ Question:

$\longrightarrow$ There are two wires of length 40 cm each .One of them has to be bend into a rectangle of length 12 cm and the other wire into a square of side 10 cm

$\bigstar$ To Find: We have to find length if rectangle.

Perimeter of rectangle= 44cm

$\longrightarrow$ Answer:

36cm^(2)

$\bigstar$ Answer : Area of rectangle= length×breadth

17cm×5cm= 85cm^(2)

121cm^(2)-85cm^(2)= 36cm^(2)

The square has more area by 36cm^(2)

$\bigstar$ Solution:

$\longrightarrow$$Area \: \: of \: \: square= a^2$

The sides of square are equal.

$So, 44/4= 11cm$

Area of square= 11cm×11cm

$121cm^2$

$Area \: \: of \: \: square= a^2$

The sides of square are equal. So, 44/4= 11cm

Area of square= 11cm×11cm

121cm^(2)

$44cm= 2(l+b)$

$44cm= 2l+2b$

$44cm= 2l+2(5)cm$

$44cm= 2l+10cm$

$44cm-10cm= 2l$

$34cm= 2l$

$34cm/2= l$

$17cm= l$

Area of rectangle= length×breadth

17cm×5cm= 85cm^(2)

121cm^(2)-85cm^(2)= 36cm^(2)

The square has more area by 36cm^(2)

★ To Find: We have to find length if rectangle.

Perimeter of rectangle= 44cm

Answer:

36cm^(2)

★ Answer : Area of rectangle= length×breadth

17cm×5cm= 85cm^(2)

121cm^(2)-85cm^(2)= 36cm^(2)

The square has more area by 36cm^(2)

★★ Solution:

Area of square=a^2

The sides of square are equal.

So,44/4=11cmSo, 44/4= 11cmSo,44/4=11cm

Area of square= 11cm×11cm

44cm=2l+10cm44cm= 2l+10cm44cm=2l+10cm

44cm−10cm=2l44cm-10cm= 2l44cm−10cm=2l

34cm=2l34cm= 2l34cm=2l

34cm/2=l34cm/2= l34cm/2=l

121cm^(2)-85cm^(2)= 36cm^(2)

The square has more area by 36cm^(2)
