Answer:

168 $cm^{2}$

Step-by-step explanation:

Consider the picture, break it into a rectangle with a triangle on top. Use the following equation to find the total area of the figure.

$A_{total}$ = $A_{rectangle} + A_{triangle}$

= length×width + $\frac{1}{2} bh$

= (12cm)(10cm) + $\frac{1}{2}(12cm)(8cm)$

= 120 $cm^{2}$ + 48 $cm^{2}$

= 168 $cm^{2}$

Answer:

1632 inches squared

Step-by-step explanation:

Hi!

So the formula for area is length times width.

So you would multiply the length by the width which is 34 times 48 to get the area which is 1632 in squared.

Hope this helps!

The area of a rectangle is 5454 in squaredin2. the ratio of the length to the width is 3 : 23:2. find the length and the width.

MrRa [10]

hello :
let : x the length and y the <span>width
</span>the area is : xy and ; x/y = 3/2
xy =5454 ...(1)
x = (3/2)y ... (2)
subsct in (1) : (3/2)y ×y = 5454
3y² = 10908
y² = 3636....continue calculate : y
