Find the area of each figure to the nearest tenth. PLEASE SHOW YOUR WORK

Mathematics

True [87]4 years ago

The first one:
the rectangle has an area of 110*140=15400
the triangle's base is (180-110)=70, and the height is 140-50=90, so the area is half of 70*90=3150
the total is 15400+3150=18550 cm²

the second one:
first, you have to find DE, which is the short leg of right triangle ADE
DE²=10²-8²=36, DE=6
DC=DE+EC=6+8=14
area of the trapazoid: (top+bottom) × height, ÷ 2
(1/2)(8+14)*8=88 ft²

Answer:

8 and 6

Step-by-step explanation:

If you use x for the first number, and y for the second, you get equations of 3x+5y=54 and x-2=y.

You can substitute the second equation into the first one to solve it. This gives 3x+5(x-2)=54.

The brackets can be expanded to 3x+5x-10=54. Collecting like terms makes it 8x-10=54.

Next, we add 10 to both sides. This gives 8x=64.

From there, we isolate the x by dividing both sides by 8, giving x=8.

To work out the second number, we can sub 8 for x in either equation (I'm using the second one as it's simpler).

This comes to y=8-2, therefore y=6.
