Question

Find the length of the diagonal of the rectangle. Round your answer to the nearest tenth.

|--------------------|
| | 8 m

|------------------- |
11 m

Answer 1

Answer:

Length  of diagonal is 13.6 m

Step-by-step explanation:

Formula for length of diagonal of rectangle is given by

$\sqrt{l^{2} +w^{2} }$

 where l is length and w is width

for this question length (l) = 11 m  and width (w) = 8 m

so length of diagonal = $\sqrt{11^{2} +8^{2} }$

                                    =$\sqrt{121+64 }$

                                   =$\sqrt{ 185 }$

                                   =13.6 m

Answer 2

If you cut the rectangle in half it forms 2 right angled triangles
You can find the diagonal by doing Pythagoras:
11^2+8^2=185
Square root of 185 is 13.6014...m
14m or 13.6 is your answer
Hope this helps
