Answer 1

Answer:

The width of rectangular blanket is 5.29 ft.

Step-by-step explanation:

Solution :

As per given question we have provided that :

• $\orange\star$ Length of blanket = 6 ft
• $\orange\star$ Diaognal of blanket = 8 ft

Here's the required formula to find the width of rectangular blanket :

$\longrightarrow\pmb{\sf{d = \sqrt{(l)^{2} + (w)^{2}}}}$

• $\pink\star$ d = diagonal
• $\pink\star$ l = length
• $\pink\star$ w = width

Substituting all the given values in the formula to find the width of rectangular blanket :

$\longrightarrow{\sf{d = \sqrt{(l)^{2} + (w)^{2}}}}$

$\longrightarrow{\sf{8 = \sqrt{(6)^{2} + (w)^{2}}}}$

$\longrightarrow{\sf{{(8)}^{2} = {(6)^{2} + (w)^{2}}}}$

$\longrightarrow{\sf{{(8 \times 8)} = {(6 \times 6)+ (w)^{2}}}}$

$\longrightarrow{\sf{{(64)} = {(36)+ (w)^{2}}}}$

$\longrightarrow{\sf{(w)^{2} = 64 - 36}}$

$\longrightarrow{\sf{(w)^{2} = 28}}$

$\longrightarrow{\sf{w= \sqrt{28}}}$

$\longrightarrow{\sf{w= 5.29 \: ft}}$

${\star\underline{\boxed{\sf{\purple{w= 5.29 \: ft}}}}}$

Hence, the width of rectangular blanket is 5.29 ft.

Answer 2

Answer:

width = 5.29 ft

Step-by-step explanation:

a² + 6² = 8²

a²  = 64 - 36

a² = 28

a = √28

a = 5.29 ft
