Answer:

The area would be multipled by 8

Step-by-step explanation:

Say you have a rectangle with the length of 5 and the width of 3, the area would be 15. Double the length, 10, and quadruple the width, 12. The area would be 120. 15 × 8 = 120.

Sorry if I'm wrong.

Find the missing side length, m.
algol [13]

Answer:

m=6

Step-by-step explanation:

The Two triangles are Similar, so using the property of the similar triangles.

                   \frac{m}{15} =\frac{4}{10}

On cross multiplication of the fraction:

                10*m=4*15

                10*m=60\\\\

Dividing by '10' both the sides:

                \frac{10m}{10}=\frac{60}{10}

                 m=6

So, the side(m) of the small triangle is '6'
