$\large\frak{ Given :}$

Diagonal of a rhombus = 7 cm and 6 cm

$\large\frak{Find:}$

Area of a rhombus

$\large\frak{Explanation :}$

$\small\tt Area = \frac{1}{2}× d¹ × d²$

Where,

d¹ = length of diagonal 1
d² = length of diagonal 2

$\implies \small\tt{ \frac{1}{2} \times 7 \times 6}$

Your family wants to purchase a new laptop with

zloy xaker [14]

Answer:

The laptop will not fit in the case.

Step-by-step explanation:

We need to find the width of the laptop to know if it fits in the case. We have:

For the laptop:

h: is the height of the laptop = 10 inch

d: is the widescreen of the laptop (diagonal) = 17 inch

w: is the width of the laptop =?

For the laptop case:

H: is the height of the laptop case = 10.5 inch

W: is the width of the laptop case = 13 inch

So, the width of the laptop can be found by using Pitagoras:

$d^{2} = w^{2} + h^{2}$

$w = \sqrt{(17 inch)^{2} - (10 inch)^{2}} = 13.7 inch$

Hence, the laptop is 13.7 inches wide.

Therefore, since the laptop is wider than the case, the laptop will not fit in the case.

I hope it helps you!
