sergiy2304 [10]

Answer:

£1000, £1400

Sum the parts of the ratio 5 + 7 = 12 parts

Divide the amount by 12 to find the value of one part of the ratio.

£2400 ÷ 12 = £200, thus

What is the area of the figure? Round to the nearest tenth.
nikdorinn [45]

Answer:

letter A

Step-by-step explanation:

This is made up of 4 triangular segments. If we assume the cross section is perpendicular then we can use the 1/2b*h formula for each piece with the given values. So we have 2 triangles with the formula: 1/2(3)*(4.5)=6.75 * 2 triangles = 13.5.

Then for the bottom 2 you have 1/2(3)*7.5=11.25, times 2 triangles =22.5

So, 13.5+22.5=36, or letter A
