The two short sides must be longer than those required in an isosceles right triangle. The ratio of side length to hypotenuse length in a 45°-45°-90° triangle is 1 : √2. So, such a triangle requires side lengths of 30/√2 ≈ 21.213 inches. Its perimeter will be about
... (30 +21.213 +21.213) in = 72.426 in
Since the perimeter needs to be slightly longer than that for the triangle to be acute, the smallest possible perimeter is ...
... 72.43 in
A = lw
A = 5.45 × 3.275
A = 17.84875
The area of the frame (without rounding) is 17.84875.
Answer:
164 and 287
Step-by-step explanation:
Their difference is 7-4 = 3 ratio units, so each ratio unit must stand for 123/3 = 41.
Then the numbers are 4·41 and 7·41, or 164 and 287.
