A diagonal of a rectangle cuts the rectangle into 2 right triangles with sides equal to the sides of the rectangle and with a hypotenuse that is the diagonal. All you need to do is use the pythagorean theorem: where a and b are the sides of the rectangle and c is the length of the diagonal.

Answer:
315 cm²
Step-by-step explanation:
Given the scale factor of 2 similar figures is a : b , then
ratio of areas = a² : b²
Here the scale factor = 7 : 21 = 1 : 3 , thus
ratio of areas = 1² : 3² = 1 : 9
That is the area of the enlargement is 9 times the original, so
area of enlargement = 35 × 9 = 315 cm²

Answer:
Step-by-step explanation:
When multiplying you use the number with least amount of significant figures in it since both 0.00045 and 0.0015 have two significant figures in them our final answer will have two significant figures in it. So the to solve and express in scientific notation we simply multiply:
(0.00045)(500,000)
0.0015 = .3375 but in scientific notation to two significant figures we write:
