Here we need to simplify the square root of ten times square root of eight, so let's write this step by step:
Step 1. The square root of ten

Step 2. The square root of eight

Step 3. The square root of ten times square root of eight

Finally, the correct option is:
<em>Four square root of five</em>
Answer:
80 sqcm
Step-by-step explanation:
area of the full rectangle is 96 sqcm (12x8) and then you subtract the area of the cutout (4x4)
If two similar triangles have sides in the ratio a : b, then their areas are in the ratio a² : b².
We have the ratio:

Area of the smaler triangle = x
Area of the larger triangle = 567 cm²
Therefore we have the equation:

<h3>Answer: C. 63 cm²</h3>
