Question

perimeter of square with side 15 cm is___________. perimeter of equilqteral triangle with side 4 cm is_______ find the area of rectangle who sides are 6cm and 8cm__________? A rectangular field is 60m× 40m. A square field as a 50m. which has more area and how much? ​

Answer 1

Answer:

1. 60 cm
2. 12 cm
3. 48 cm²
4. square's area is 100 m² more than rectangle

Step-by-step explanation:

1.

perimeter of square = 4×side

= 4×15 cm

= 60 cm

2.

perimeter of equilateral triangle = 3×side

= 3×4 cm

= 12 cm

3.

area of rectangle = length × breadth (side1 × side2)

= 6 cm × 8 cm

= 48 cm²

4.

area of rectangle = length × breadth

= 60 m × 40 m

= 2400 m²

area of square = side × side

= 50 m × 50 m

= 2500 m²

so square's area is 100 m² (2500 m² - 2400 m²) than the rectangle.

hope it helps.
