Sean is making a mosaic using tiles in the shape of right triangle. Each tile has leg measures 4 centimeter and 6 centimetres. W
Makovka662 [10]

Answer:

12 centimeters^{2}

Step-by-step explanation:

Length of first leg of a Right angle triangle= 4 centimeters

Length of second leg of a Right angle triangle= 6 centimeters

We have to find the area of tiles

Area of tiles= Area of  Right angle triangle

Area of a right angle triangle= \frac{1}{2} × base × Height

Area of a right angle triangle= \frac{1}{2} × 4×6

Area of a right angle triangle=12 centimeters^{2}

Hence , the correct answer is 12 centimeters^{2}

the lengths of the sides of a triangle are in the ratio 5:6:7. describe the length of the longest side if the perimeter is less
Alex17521 [72]
Adding the parts in the ratio gives 18 so there are two triangles possible with perimeters less than 54cm where the side lengths are all integers: a 5, 6, 7 triangle or a 10, 12, 14 triangle.

Therefore the length of the longest side must be either 7cm or 14cm (unless you want to include non-integer side lengths, then it could also be 3.5cm, 1.75cm etc)
