Ann [662]

Answer:

$width=10\sqrt{15}\ in$

Step-by-step explanation:

-A rectangle's area is given by:

$A=lw\\\\l=length\\w=width$

Given A= $30\sqrt{3750}$ and $l=3\sqrt{250}$ , we substitute in the formula to solve for the width as follows:

$A=lw\\\\30\sqrt{3750}=3\sqrt{250}\times w\\\\w=\frac{30\sqrt{3750}}{3\sqrt{250}}\\\\w=10\frac{\sqrt{3750}}{\sqrt{250}}\\\\=10\times \sqrt{\frac{3750}{250}}\\\\=10\sqrt{15}\ in$

Hence , the rectangle's width is $10\sqrt{15}\ in$

1) c= 3.5cm × 22/7

c= 77cm/7 = 11cm

2) c= 2×3.14×5cm

= 6.28× 5cm

=31.4cm

3) L=180/360 × 22/7 × 3cm

= 1/2 × 22/7 ×3cm

=4.71 cm

4) c=12cm ×3.14

=37.68cm

5) c = 4.5cm × 3.14

=14.13cm
