The cross-section of a canal is in the form of a trapezium. If the top of the canal is 15 m wide, the bottom is 8 m and the area of cross-section is `138m^2`, find its depth.

The cross-section of a canal is a trapezium in shape. If the canal is 10m wide at the top 6m wide at the bottom and the area of cross-section is 72m^2 determine its depth.

The cross-section of a canal is a trapezium in shape.If the canal is 10m wide at the top 6m wide at the bottom and the area of cross- section is 72m^(2) determine its depth.

The shape of the cross section of a canal is a trapezium. If the canal is 10 m wide at the top, 6 m wide at the bottom and the area of its cross section is 640 m^(2) , find the depth of the canal.

The shape of the cross section of a canal is a trapezium . If the canal is 10 m wide at the top , 6 m wide at the bottom and the area of its cross section is 640 m^(2), find the depth of the canal .

The cross-section of a canal is a trapezium in shape . If the canal is 20 m wide at the to pand 12 m wide at the bottom and the area of the cross-section is 640 sq m, find the length of the cross-section.

The cross-section of a canal is trapezium in shape. The canal is 12 m wide at the top and 8 m wide at the bottom. If the area of the cross-section is 840 sq. m, the depth of the canal is (a) 8.75 m (b) 42 m (c) 63 m (d) 84 m
