 1. Find the area (in m²) of an isosceles triangle, each of whose sides is 10 m and base 12 m. .fixedToBottom { position:fixed; _position:absolute; right:0; bottom:2; _top:expression(document.body.scrollTop+document.body.clientHeight-this.clientHeight - 256); } Hint 2. The ratio of the areas of two triangles is 2 : 3. The ratio of their heights is 3 : 2. If the ratio of their bases is 4 : y, what is y? Hint 3. The base of an isosceles triangle is 24 cm and perimeter is 64 cm. Find its area (in cm²). Hint 4. The base of a right-angled triangle is 5 cm and its hypotenuse is 13 cm. Find the area (in cm²) of the triangle. Hint 5. Calculate the area (in cm² upto 1 decimal place) of an equilateral triangle of side 10 cm. Hint 6. The area of a right-angled triangle is 30 times its base. What is its height (in cm)? Hint 7. Calculate the height (in cm to the nearest integer) of an equilateral triangle whose area is 36.95 cm².
